Abstract

An apparatus, named KGbox-24, which enabled one to measure rat's eating, drinking, rearing and locomotive activities over 24 h a day was introduced. The effects upon these behaviors of shocks given at 2100 hours, or at one hour after the beginning of the 12-h dark phase, were studied over 10 days, with a single rat. Using the results of this rat for an illustrative purpose, the methods to analyze both the local and overall effects of shocks and to quantify the patterns of behaviors over a wide range of time were introduced. There was evidence of a development of conditioned suppression of eating and drinking during the first hour of the dark phase. The suppressing effects of 2100 hours shocks upon eating and drinking also gradually spreaded bidirectionally along the temporal dimension from 2100 hours. Although the factual aspects of the present study have to be ascertained in future, the present apparatus and the analysis-methods seem to be promising for the future studies of rat's adaptive processes in an aversive situation.
